Bug Fixes
The following issues are fixed in this release.
CQL
- Empty values of fixed-size CQL types (such as
int,bigint, ortimeuuid) are now correctly handled when used as clustering key components or nested inside frozen collections, tuples, or UDTs. Previously, such values could cause incorrect ordering, an internal error, or a garbage result. The fix aligns the encoding behavior with Cassandra.

Networking
- In rare cases, RPC stream decompression could produce corrupted data, surfacing as checksum failures on production clusters. The decompressor now uses a correctly sized buffer, eliminating the corruption.
scylladb#31034
Storage
- Object storage uploads and downloads did not correctly handle empty (zero-length) components. On writes, an empty upload sink produced no object at all, which could cause subsequent upload steps to fail. On reads, an empty object could not be read back due to an unsatisfiable byte-range request. Both cases are now handled correctly.
